high fidelity listening room

It involved screwing and gluing, rather than nailing, the wall structure together. Move a few feet away from the door and the sound is barely detectible. When standing in the hallway in front of the door with music playing at a high level in the listening room, you can detect that music is playing on the other side but it’s not nearly loud enough to disturb anyone. Example room setups (critical listening / mixing rooms) Below are three example rooms we’ll be looking at. My description of the room’s AC power a few issues ago prompted more than one reader to accuse me of elitism (“That was the most elitist bunch of crap I’ve ever read. The sound had a solidity in the bass, a sense of effortlessness on dynamics, and an expression of music’s rhythmic flow that I had not heard before from this equipment. I wanted to be able to listen to any music, at any hour of the day, at any listening level. (The electrician and project foreman both thought the AC power requirements were bizarre and unnecessary—not to mention their opinion of the Iso-Wall construction.) Wonder what a multimillion-dollar room looks like? A bay window hidden behind the curtains disperses the lengthwise room mode by varying it between 18' and 20.6'. The tool plots all the resonance modes graphically, shows you if the resonance distribution meets the “Bonello Criterion,” and suggests ideal ratios, among other analyses. Attaching the resilient channel to the ceiling is particularly challenging for one person. High Fidelity Design Group | High-End Audio Austin, TX - HiFi | High-End Audio | Amplifiers | Speakers | Turntables I had always assumed that this was simply part and parcel of reproduced music—a characteristic of amplifiers being pushed, or the mechanical structures in loudspeakers reaching their limits. The next step up is to use 2×6 plate with 2×4 studs that are staggered. I specified five dedicated lines for equipment-placement flexibility. I also used the Acrolink 8N-PC8100 Performante Nero Edizione cable. I was beyond shocked by what I heard. 8 shows my room with the channels installed. When standing in the hallway in front of the door with music playing at a high level in the listening room, you can detect that music is playing on the other side but it’s not nearly loud enough to disturb anyone. You can also hang vinyl material inside the wall for even greater isolation. Accessibility, with respect to home integration, is typically gained through a mobile device such as an iPad or iPhone. Go to keithyates.com to see what’s possible at the state of the art. 1). This is also the reason, that the HRS-120, and other loudspeakers from this company, MUST happen in our listening room, and not only in an audio salon. In order to keep with a long tradition, we also awarded Best Sound awards. Watch for upcoming reviews. I recently realized a lifelong goal of building a serious listening room and will share my experience with you. The framed structure is rendered quiet and inert. It doesn’t take much wall motion to hear tonal coloration because the acoustic output of a vibrating object is a function of the object’s excursion (how far it moves) and its surface area. The finished and painted room looks just like any other room in the house—the acoustic infrastructure is completely invisible behind the drywall. The plan included other non-standard and labor-intensive framing techniques. I’ll share with you just a few examples of the vast range of wall constructions. Nonetheless, in my application the door is highly effective and in practice works as intended. On the peaks the sound congeals; individual instrumental textures tend to be smeared into a single big sound; and the sense of space collapses. I hit an undamped stud with a hammer and listened to the ring. The room’s five dedicated 20-amp AC outlets for the audio system are wired with identical lengths of 10AWG on the same phase. Did I go far enough? I followed the guidance of Shunyata Research founder Caelin Gabriel in specifying my room’s power. Generally, the larger the room the better the sound (assuming good dimensional ratios); a large room spreads out the resonance modes more smoothly than a small room does, resulting in flatter bass. I made reference to convenience and its unintended consequences, with respect to digital music playback, in my post: “Computer Audio at Its Finest.” There are serious tradeoffs when convenience takes precedence over quality. This technique was developed about 25 years ago by Art Noxon and has been used successfully in many listening rooms and recording studios around the world. I cannot stress enough that two-channel applications require an entirely different and specialized skillset than that of home theater. Called the ASC Iso-Wall System, it is a building method that achieves excellent isolation of the listening room (sound proofing), nearly eliminates wall shudder, and absorbs excess bass. The size, i.e. The Absolute Sound is the world’s preeminent source of expert reviews, features, and commentary on high-performance audio and music. You can see an overview of the entire Iso-Wall structure in Figs. The walls adjoining the hallway and garage are framed 2×6. High Fidelity offers patented Live Spatial Audio solutions, including virtual spaces to gather online and APIs for developers. Until you set up a pair of speakers in the room and listen, there’s no way to know how the room will sound. You’re now ready for the second and final layer of drywall, which is also installed vertically and with its seams offset from those of the first layer. After discovering the importance of the listening room’s contribution to sound quality, I consider it another component in the signal path and will list the ASC Iso-Wall System as part of my reference system in future reviews. The goal is to make the room as inert as possible, reducing the amount of wall resonance and shortening the decay time of the resonances that remain. The higher the number the greater the wall’s attenuation of sound. Good room ratios spread out the room’s resonant modes more evenly, resulting in smoother and more linear bottom octaves. The resilient channel is attached to the studs, and the drywall to the resilient channel. But it was only after living with the reference system (see sidebar) and its much deeper bass extension and wider dynamic scale that I came to fully appreciate the room’s contribution (or more precisely, lack of contribution) to the sound.

Again, the drywall is screwed through the two drywall layers into the resilient channel, making sure that no screws penetrate the studs. I would implore anyone reading this article that loves music as much as I, to ask themselves where their priorities lie? Would the room sound any better than a conventional room? I went through 17 tubes of oversized (29-ounce) acoustical caulk. Convenience is what drives the trend to combine one’s listening room with their film room. It was a wholesale transformation, not a matter of minor improvements in a few areas. If you have the chance to build a house, the cost of ASC’s Iso-Wall is without question the best allocation of your audio budget. The central area of each wall essentially “floats” on the flexible resilient channel rather than being rigidly affixed to the studs. You can see the black perimeter gasket and white wall-bearing felt in Fig. High-fidelity: Webster's Timeline History, 1931 - 2007: 28,95€ 2: High Fidelity: 1,29€ 3: The 2021-2026 World Outlook for High Fidelity (Hi-Fi) Systems: 895,00€ 4: The Sound of Pictures: Listening to the Movies, from Hitchcock to High Fidelity (English Edition) The trend is to compartmentalize, combining technologies that are easily accessible and, as it relates to home entertainment, within one location. The channel is laid out in horizontal strips across the studs and screwed to each stud it crosses. I’m hearing those qualities in the new room, and I speculate that it’s because the Iso-Wall structure is doing for the listening room what the inert speaker cabinet did for the loudspeaker—reduce the low-level chaotic motion that imposes a threshold below which information cannot be resolved. After the bass clarity and dynamic fidelity, the next most dramatic and musically significant aspect of the room’s performance is the absence of this phenomenon. For a nominal additional cost you can use 5/8″ Type X Sheetrock on the wall outside the listening room and gain a few dB of additional transmission loss. With music playing at a moderate level inside this room, standing just outside the room you would be able to clearly hear and identify the music. As a result, the sound had a delicacy and density of information that accurately conveyed instrumental timbre, while also vividly portraying the size of the recorded acoustic and the spatial perspectives between instruments and between the ensemble and the surrounding hall. A small tweak is to specify different densities of drywall for the two layers. I also would have hired someone to help me with the installation; it’s a huge amount of work for one person, particularly one whose day job is largely sitting at a computer. As Art Noxon explains in the sidebar, however, soundproofing and optimizing audio quality inside the listening room is more complex than simple soundproofing. The solid-core door performed much better than I thought it would, attenuating the sound quite well. The materials cost for my room was about $13,500—$8500 for the ASC Iso-Wall products (ASC supplies a kit with the appropriate amount of dRC-1 and dRC-2 resilient channel, WallDamp strips, squares, and StudPacks, perimeter gasket, and wall-bearing felt,), $4000 for the isolation door, and $1000 for plywood stud dampers, screws, acoustic caulk, and miscellaneous supplies. (The room’s main door opens to a hallway in the house.) I know people who have spent on their AC ground more than I spent on my entire room—it involved, in part, a copper ground rod buried in an electrolytic slurry of precise chemical composition that must be constantly kept moist. The same goes for tubes. Remember that the resilient channel allows the interior surfaces of the listening room to bend but not vibrate, which is a key element in a constrained-layer damping system. A standard 2×4 wood-framed wall (16″ on-center) filled with insulation and with 1/2″ gypsum board (drywall) on both sides is specified as STC-35—not a very high value. Instead of the kick drum sounding like a low-frequency thump, the system conveyed details about the mechanism by which its sound was created, including the beater hitting the drum head and the resonant ring of the drum. I did, however, adhere to Art Noxon’s specification that I damp the 2×6 studs by attaching strips of 5″-wide and 1/2″-thick plywood to the side of each stud, with two strips of ASC’s WallDamp, a self-adhesive viscoelastic damping material (Fig. A room that is designed to diffuse sound is optimal for two-channel applications. The third-car garage is a staging area for gear coming and going, as well as facility for box storage—a surprisingly important consideration for reviewers. Their sound vibrates in us just like when listening to live instruments, especially if we are in a small room with them - just like in our listening rooms. Room 1 (Left): A lightly treated 2-channel mixing room with basic absorption and diffusion (typical in a project or home recording studio). Then WallDamp Squares (4″ by 4″) are applied to the drywall face 12″ on center (Fig. The Wilson Benesch Eminence loudspeaker has extraordinary bass articulation on its own, but I could hear that the room was allowing this speaker to reveal nuances of texture, dynamic shadings, and pitch that I’d never heard before on familiar recordings. When designing a listening room, most of our budget should be dedicated to these speakers, as they are the main actors! But overall, it was well worth the research, time, effort, and expense. Such an experience allows the listener to quite literally transcend spacetime, teleporting them to witness Beethoven’s 9th, the orchestra and choir before you in their respective positions. See more ideas about fidelity, audiophile listening room, audio room. The speaker also resolved very low-level textural and spatial cues that were lost by most loudspeakers. AC power to the listening room is supplied by a separate sub-panel located right outside the listening room. I’ve heard this track on many systems, but never one like this. When the wall is flexed by the acoustic pressure of low-frequency sound inside the room, sheer forces in the viscoelastic layer dissipate that energy as a minute amount of heat in the viscoelastic material. The Iso-Wall construction technique solves the three main problems with listening rooms: 1) it greatly reduces wall shudder; 2) prevents sound inside the listening room from getting out; and 3) absorbs excess bass energy by virtue of the flexible walls, turning them into giant membrane bass traps. Furthermore, most home theater rooms are acoustically treated for their primary purpose, film!
